This inventionrelates to means for; forming lease sheds in moving warpsand; placingcand inserting leasethreads' through said warps while beingwound from one form of package intoanother, without stopping movement ofthe warps; and it hasfora primary object theprovision of a,novelrnechanism whereby the sheds are concurrently formed and so heldfor insertion .of the, lease thread. Another object is to provide aleasing mechanism withmeans permitting closing of the sheds upon thelease thread and forireeingsaid thread for travel with the warps. 1

, further object is to provide a novel mechanism for the indicated,purpose which is auto-' matically actuated, at, the predeterminedintervals, and similarly or-manually restored to leaseforming, positionin. an, expeditious manner, with incidental increase in theoutput and a,better quality of the work. i i V r stated andother objects, aswill"herein-- after appear, are attained by themechanism illustrated inthe accompanying drawings, wherein like characters of reference areapplied to corresponding parts in all the views; while the novelfeatures are more particularly expressed in the claims atv theconclusion of this specification.

Referring now, more specifically, to Figs. II VI, the novel leasingmechanism l of this in-' vention is conveniently sustained by spacedstandards or side frames l2, maintained in parallel relation by asuitable roller-like tie l3, and a warp-separating" roll I4. ,Jour'haledin bearings l5 on the side frames l2, intermediate the tie I3 andwarp-separating roll, I4, is a two-part shaft I6, l6 operatively.coordinated to said roll, at one side of the mechanism; by levers l1,l8, rigidly attached to the shaft section it with a connectingdink- [9;while the shaft section It is conveniently, althoughnot essentially,fitted at the other sideoi said mechanism, with anappropriatemanipulator or said shaft l6 may be operatively connected toany suitable intermittently-activatedpower means (not shown) in anobvious manner. The manipulator 20 may, preferabl-y; be in the form ofa'lever suitably attached to the outer end of the shaft section [6, witha weight 2| atone end, and a hand grasp 22 at the other end, with saidweight adapted to hold the, mechanism I, out of action, as later onexplained. V

The two-part shaft l6; 16' has secured to its spaced inner confrontingends crank members 23 between which is disposed the novel form ofleasing-reed 24, consisting of a series of com bined warp separating andshed-forming elements or thin plates 25, with intervening spacer washers26,121 and pins 28. Each plate 25, as best understood from Figs. IV, andV, is of special contour, that is" to say, it embodies an arcuate edge29: preferably of a radius coinciding with theaxis of rotation of thetwo-part shaft l6, I6; an eccentrical-ly related curvature 30 ofsubstantially greater radiusto provide easy release for the leases whenknotted; apair of leasethreadengaging notches 3|, 32; a warp spacing tip33; and a plurality of apertures 34,. 35-through which clam-ping means,-such as bolts 36, 31 are passed, as well as through the spacing washers26,21, torespectively secure saidplates to the crank members 23- andtoone another. It is to be particularly noted, at this juncture, that thelease thread engaging-notch 32 is well inset relative to that part oftheplate 25' through which the clamp bolt 31 passes; the radius of theplate arcuate edge 29 and the j'ournaling of the leasing reed 24 is suchthat the latter rotates in close proximity to the warp separating rollI4; while the-notches 3l 37.,uwherr the leasing reed 24 is assembled,constitute spaced or parallel open passageways respectivelyto each sideof the axis of rotation of said leasing reed. The tips 33 of each pairof adjoining plates 25 are suitably merged to meeting relation andpermanently united thereat, as well as rigidly connected by the spacerpins 28 aforesaid, so as to form alternatingly open and interrupted warpreceiving dents 3B, 39, respectively, between the several plates 25, fora purpose later on set forth.

Threadedly engaged in the warp-separating roll I4 and flanking the sidesof the leasing-reed 24, are angular guide-holding members 40 which arerounded at their crotches 4|, and rigidly retained at the requisiteradial adjustment, relative to the axis of the roll l4, by lock nuts 42.The free angular ends 43 of the member 40 are of a linear dimension andinclination such that their termini serve as stops for engagement by thehead and nut of the clamp bolt 31, to limit clockwise rotation of theleasing reed 24, While the ends of the leasing thread 44 are being tiedtogether.

A suitable comb 45 is, preferably, arranged in spaced relation to thewarp separating roll l4, in order to prevent lateral displacement ofsaid warps during the leasing operation, while 46, Fig. VI, designatesthe leasing knot.

In order to hold the leasing reed 24 in the operative position of Figs.II and IV, there is secured to the shaft section l6 at one side of theleasing reed 24, a dog 41, the free end whereof is adapted to coact withthe tooth portion 48 of a pivoted catch 49. The other end of the catch49 is pivotal at 50 to the core extension of a solenoid 52 in circuitwith, and under control of, the counter 1, as shown in Fig. I; and 53designates a stop projecting from the adjoining side frame l2 with whichthe dog 41 engages to limit counterclockwise movement of the leasingreed 24, when it is released and swings to the inoperative position ofFigs. III and V.

The manner of forming a lease with the thread 44 is as follows. Thewarps I I from the spools 3, after leaving the warper 4, pass throughthe comb 45 alternatingly over and under the warp separating roll l4 andare threaded through the leasing reed 24; half of said warps beingdisposed in the open dents 38, and the other half in theinterrupted-dents 39, so as to be engaged by the cross pins 28 asclearly understandable from Figs. IV and V, whereupon said warps passunder the tie or guide l3 to the header roll 6, thus normallymaintaining lease sheds respectively at opposite sides of the axis ofthe leasing reed 24; and from thence to the winding unit 3,- forformation of cheeses l0. Incidentally it will be apparent that thespacing tips 33 of the leasing reed 24, as the latter is rockedclockwise, readily pass between the warps H and effectively hold themagainst lateral displacement, with respect to the warps elevated by thespacer pins 28. Now as will be readily understood from Figs. II and IV,that with the warps alternatingly divided there will be concurrentlyformed at opposite sides of the axis of rotation of the shaft l6, I6sheds S, S as a result of the elevation of the one-half of said warps inthe dents 38 by the spacer pins 28. Furthermore, with the lease formingmechanism in its normal position, as shown in Figs. II and IV, and soheld by the dog 41 and catch 49, the guideholding members 40, as well asthe lease thread passageways 3|, 32 will be in position to permitthrowing or insertion of the leasing threads or thread 44 through saidpassageways. The lease loop is then formed by tying together the ends ofthe thread as at 46 with the rear end of said thread extending aroundthe backs of the holder projections 43.

After predetermined lapse of time corresponding to a definite length ofwarps, solenoid 52 is automatically energized under control of thecounter I, and the dog 41 released under oscillation of the catch 49,induced by attraction of the core extension 5| inwards of said solenoid.Thereupon by influence of the weight 2| to the manipulator 20, theleasing reed will automatically swing from the position of Fig. IV tothat of Fig. V, with attendant closing of the leasing shed S in upon thefront strand of the leasing thread 44, and release of the rear strand ofsaid thread by the holding elements 40. The leasing loop being now freeof restraint will thereupon be carried along by the moving warps Theparts 41, 48 will then be returned into holding coaction by the operatorswinging the manipulator 20 clockwise, in an obvious manner, whereuponthe leasing reed 24 will be placed in position ready for the nextleasing operation after a conventional run of the warps II, for exampleevery fivehundred yards.
